The
following is an excerpt from the book The Healing Clay by
Michel Abehsera:

A person who observes
nature can witness the fact that animals instinctively use earth to
cure themselves. Indeed, we owe much of our discovery in this
field to animals. There is a sea resort in the Siberian forests
of the Oussouri where the discovery of the curative properties of the
earth was the result of observations of wounded animals, wild pigs,
roe-deer, red deer and other animals who came to wallow in the
benefactory mud. Dr. Em. Grommier has told the story of the
elephant "Fil," who, with his kindred, purged himself with
silicic-magnesic clay-marls and daubed himself with mud.

The French Army used
it recently for veterinary purposes - when horses were afflicted with
hoof gangrene, they were put in a stable, the floor of which had been
dug up and kept wet so that the horses could kick in the mud.
The animals went instinctively to the clay-mud where they found a
remedy for their disease.

Animals seem to know
instinctively the usefulness of contact with clay when they are ill or
wounded. Those living wild to not hesitate to dip the affected
area in mud. Domestic animals, too, turn to clay. A cat
that is abscessed, wounded or ill will lie on a clay case (a large bin
of clay covered with a cloth). Even when not ill, she will
prefer this bed to one more comfortable.

Domestic and farm
animals can be treated with clay. The method of treatment is the
same as for human patients, the only difficulty being in the docility
of the animal in accepting the treatment. Farm animals can be
persuaded to dip themselves into a mud bath prepared by digging a
large enough hole filed with clay and water. Cows have been
cured of foot-and-mouth disease (apthous fever) with applications on
the feet and daubs in the mouth. In certain countries, seriously
ill animals are saved by daubing them completely with a mixture of
clay and vinegar. Good results are also obtained by replacing
vinegar with very salted water (sea salt).

For internal use,
clay is also effective. It can be added to the drinking water (4
soupsoons per quart of unboiled water) and even mixed with food.
It can be used in the fur - particularly for cats, who constantly lick
their fur, thus absorbing it easily.
